I'm actually impressed it will run at all on six cylinders. You should take some video/audio for us to check out.

No one in my family has owned a V-12 in quite a long time -- a fact directly related to the fact that none we ever had reliably ran on more than 10 or 11 cylinders anyway. Life with Italian motors, I suppose... Never had a cylinder drop out on a V-8.

Cheers, John

90% of the time this kinda thing corrects itself without intervention...give it a few days to dry out.

Check the cavity where the coils and plugs reside...this is typically where water manages to penetrate and pool.

Try to remove as much standing water as physically possible. A wet-dry vac or compressed air hose works well.

If I had a nickel for every non-useful post to an internet forum thread, well, I would have just made myself five cents richer.

Loosen up. And good luck getting her to hit on all twelve. Not gonna beat that Ferrari in a race on half your cylinders... Or anyway.

Cheers, John

Actualy the M120 is famous for that. It will run perfectly fine on one bank, all you notice is a lack of power.

I'd have the codes scanned and see whats going on. Throwing parts at an S600 is a very bad idea.

I believe it is designed to do that as a part of it's "limp home" mode.

I'd suggest checking the coils to see if any are wet on the side that is not firing.

In your climate it may well resolve itself in a day or two with the hood up.
